AIX 5.3 to 7.1 migration process?
Im having a little trouble deciphering the best approach to perform a SAN booted lpar (clariion) aix migration.
Currently lpar has dedicated HBA's connected to clariion array. With the following ODM/powerpath filesets installed.
| EMC.CLARiiON.aix.rte | 5.3.0.3 COMMITTED EMC CLARiiON AIX Support |
| EMC.CLARiiON.fcp.rte | 5.3.0.3 COMMITTED EMC CLARiiON FCP Support |
| EMCpower.base | 5.1.1.0 COMMITTED PowerPath Base Driver and |
EMCpower.consistency_grp 5.1.1.0 COMMITTED PowerPath Consistency Group
EMCpower.migration_enabler
| EMCpower.mpx | 5.1.1.0 COMMITTED PowerPath Multi_Pathing |
AIX 7.1 requires ODM v6 but it doesnt look like ODM v6 will run on AIX 5.3. Since powerpath is installed as well, whats the official process for migrating aix?
Do I uninstall powerpath, migrate to aix 7.1 install new ODM and then reinstall new version of powerpath? Any tricks or gotcha's?
